INSEAM JOINT FORMING MACHINE Filed Aug. 30, 1941 Fig: 18.

9 Sheets-Sheet 9 marginef the.insole and beyond the line of the insole ribinorder to flatten the entire width of the lasting margin at that portion of the upper against the. insole to facilitate the subsequent heel'end lasting operation. In the illus-. trated machine, the novel flangeforming' mechanism'includes a flange former which advances from a remoteposition widthwise"of the shoe inwardlyover theinsol'e rib at-an elevation well above the shoe, then heightwise of the shoe. into engagementwiththe insole and finally outwardly J into flange-forming engagement with the insole;

insole on a, last bottom by an initialmovement bodily widthwise only of the last and by a subsequent swinging movement about anaxis extend- 'ing generally heightwise of the upper after the initial movement is completed. r

In another aspect, the invention resides in the provision in a shoe machine of a member for operating on a shoe bottom, a. carrier on'which said member is 'mounted'for relative movements both heightwiseand widthwise of the shoe, means 'ior'moving the carrier toward the shoe and means j for-moving said member heightwise into engagerib, In accordance-with a further feature'of the invention, the abutment member and the flange former are so constructed. and arranged that their work-engaging surfaces extend upwardly with an outward'inclination so as to overmold the upper materials, particularly the counter flange,

to an extent commensurate with the normal P initial overwiping movement to the wipers after which the carriers moveyrelatively to the slides to complete. the opcrationcfthewipers. In the illustratedmachine, the carriers moverelatively to the slides in arcuate paths toimpart swinging movement to the wipers about axes coincidental with the. ends of the-insole rib.

Toassist inthe formation. of a well defined angle inthe flange, of thecounter and the overlasting. margin of the upper, the illustrated wipers, in accordance with a further feature of theinvention, areprovided with beads extending downwardly. from. their wiping, edges and means issprovided for efiect'ing relative -movement of the wipers a'ndthe shoe heightwise of the shoe to causesaidibeads to indent the work.. As herein illustrated, thelwipers are held against heightwise movement. while-1a work support is moved up- 'wardlyabypower-to iorce the shoe against the ment with tl ie' shoe bottom'then widthwise of the shoe. Said member, as herein illustrated, is the "fiangeior'mer whichacts against the inner suriaceof' the insole rib. It'will be understood, jhowever, that a member other than a flange,

former could be incorporated in this combination 7 Without departing from the invention.

These and other-features or the invention will nowbe described with reference to the accompanying drawings and pointed out in the appendedclaims. I

Inorder that the operating instrumentalities at opposite sides of the shoe. may. advance until each has-been arrested by engagement with the shoe, the .shaft' I22;is so-constructedand arranged that after the operating instrumentalities at one side of thema chine are arrested-by engagementwith the shoe, saidtshaft, is moved endwise, by .1 reason of the operative movement of the wormIZfl at that side of the machine-with relation to the stationary worm gear. During-such endwise movement, the

shaft and the operating instrumentalities at the opposite side of themachine are advanced independently until they, too, are arrested byengagement with the shoe.

Both the inward movement of the, slides 53 and the arcuate movement: of the' blocks I68 areefiected by the-'inwardmovement of the :arms I56'produced by the operationof theworms I24. To

this end, each slide I58 carries a sliding pin I12 (Fig. ll) which is.mounted in a hollow' bracket QI'M secured to the slide I58 and connected to'the arm I56 by a link I16 pivoted on a short shaft I'I.8..(Figs.":1l'and ld) mounted in a head Ilon' V the pin I121.
